UNITED STATES PATENT QEEICE.

ROBERT Pf GARSED, OF NORRISTOVVN, PENNSYLVANIA.

ANNUNCIATOR.

SPECIFICATION forming part of Letters Patent No. 428,810, dated May 27,1890.

Application filed January 25, 1890. Serial No. 338,140. (No model.)

To all whom it may concern.-

Be it known that 1, ROBERT P. GARSED, a citizen of the United States,residing at Norristown, in the county of Montgomery and State ofPennsylvania, have invented a new and useful Improvement inAnnunciators, of which the following is a specification, reference beinghad to the accompanying drawings to more clearly illustrate theinvention.

Theobject of my invention is to produce an annunciator that can beworked either pneumatically, electrically, or otherwise, and with as fewand as easily-worked parts as possible, and to simplify its recoveringand indicating mechanism, which heretofore has been more or lesscomplicated as well as cumbersome. It further has for its objectimprovements in its alarm-working mechanism.

Figure 1 represents a front View of the device; Fig. 2, a side view ofthe same, showing the inside of the case; Fig. 3, a sectional view ofthe bellows and their collapsing weights,

as well as their supporting-brackets. Fig. 4: is a top view of a sectionof the front of the case, showing the lifting-rodswith their proj ectingarms and the index-cranks resting 011 the bellows. Fig. 5 is a view ofthe lifting-rods with a section of outer one removed, showing theposition of the inner one. Fig. 6 shows a screw which when in placesupports gong-staif and holds as well the end of coilspring shownbeneath it. Fig. 7 is a side view of the bellows-bracket used, and Fig.8 a top view of the same. Fig. 9 shows a modification of the alarm. Fig.10 shows the flexible band Z, used for revolving the escapem entwheelshaft; and Fig. 11 is a sectional eleva tion showing magnets substitutedfor bellows, and Fig. 12 is a detached perspective View showing magnetsand their connecting parts. In these means for operating the deviceelectrically, (shown in Figs. 11 and 12,) the actuating element ormagnet 0 corresponds to the bellows G, and the electric-fluid conductorsS, leading to within the case, correspond to the air-conductors S.

Referring to the drawings, A is an annunciator-case, with anupwardly-proj ectin g back supporting alarm mechanism, and a face Asupporting the indices with their actuating machinery.

B is a gong adapted to sound upon the influx of air into any of thebellows O.

D are the indices adapted to move in the operation of the device, andhaving cranks or ends D passing to the other side of face A.

E is a hollow lifting-rod-with projecting or engaging arms E.

F is an index lifting or restoring rod having projecting or engagingarms F.

O is an inner bellows-collapsing weight, with a central threaded stemextending upwardly through the top of the bellows, and holds the outercollapsing-weight G in position, as well as making an air-tightconnection. The outer weight has a downwardlyprojecting rim G and anupwardly-extending center G, which tends to guide the bellows in itsmotions by passing through the openings in the projecting arms E of thelifting or alarm-actuating rod. This interlocking is furtheradvantageous, as when these arms have been raised by any one bellowsthey in turn find their central position when descending upon the otherbellows by such centers Gr being tapered.

II is a slot, and when right and left indices are used is made throughboth sides of the outer lifting-rod.

B is a bifurcated gong-staff and equalizes the weight of gong B upon thebrackets J. It has feet I on either side held in position to thebrackets by screws, as shown, the one screw on the right being adaptedto hold one end of spring K in position as well. The other or inner endof said spring being fastened to shaft Ii causes it to return to itsnormal position after it has been revolved by the upward motion of thelifting-rod E, at the upper end of which is fastened the end of aflexible band Z, whose other end is attached to shaft L, with itsintermediate part wound around said shaft. The escapement-wheel M, withits pawl and ratchet-wheel N, being connected to work together inturning one way, and being also 011 shaft L and gearing with thepallets, causes the attached hammer to vibrate and sound the gong in theoperation of the device. Further explanation of the working of any ofthe bell-ringing apparatus is unnecessary, as part of it is well known.The feet I I of staff B being at angles with said staff hold it betterto a fixed position necessary for accurate operation of the gong, thebifurcated staff being also essential to give a fixed position to thebrackets J, that they may not spring inwardly or outwardly and affectthe movements of shafts L and O, the stud I also contributing to thisresult.

The cranks l) of the indiees,itwillbe seen, have weight on the otherside of their pivots opposite their bellows-en gaging end, that they mayby a small rise of the bellows act by gravity in completing their fullmotion.

R are the bellows-supportin g brackets,which will be seen to be made ina space-saving and economical way, obviating any bend in theair-supplying pipes S, with which they are connected, such bend of pipebeing object-ionable, and when made underneath the brackcts taking upmuch valuable room, as well as being liable to be injured in adjustingthe device.

T are the air-channels of the brackets, and U are the flanged couplingsof the bellows for connection of brackets, as shown inv Fig. 3. They arefirst inserted through an opening in bottom of bellows and then screwedinto the brackets, the center of coupling having an opening for passageof air.

The weight G, with dowmvardly-projectin g rim,if not heavy enougl1,1naybe re-enforced, as shown in dotted lines in Fig. 3. The downwardly-projeetin g rim, besides saving vertical space, renders the bellows lessliable to unsteadiness of motion when rising or falling, its collapsionalso being best accomplished by the weight bearing as well upon abroader fold than the top. The weights when rising and engaging theindex-cranks are also less liable to tilt.

The Spring with an eye on its end, as shown by dotted lines, to slipover end of the screw; otherwise its end may be flat and slip within theslot.

The operation of the pneumatic device is as follows: Air being forcedthrough any of the conductors or pipes S in any of the usual ways bymouth-piece or pump enters through the channels T of the brackets R tothe inflatable body or bellows C, and inflating the same causes thecrank l) to rise and move the index I) to a desired position, thusindicating the source of operation. The liftingrod E, risingsimultaneously with the movement of indices, through the medium of itsprojecting arm E engaging the top of the bellows, causes the alarm tosound, as before described, and so calls the attention of a properperson, the rod E returning to its first position as well by gravity asby the operation of spring K. The crank 1) having been moved to aposition indicated by dotted lines on' the left side of Fig. 3, theindex is returned to its normal position by raising the index lifting orrestoring .rod by prcssingupwardly upon the knob at its lower end.heneath the bottom of case A. The projecting arms of this restoring-rodwill then engage and return to their normal position any cranks shown inFig. 6 may be made that have been operated. Instead of projectinglaterally, these crank-moving arms may extend, if desired, through theface A and engage directly the indices. The inner collapsing-weights Ooccupy room otherwise unused, and hence are advantageous in contributingto the collapsion of bellows after they have been made to rise.

In practice the bellows -brackets can be placed much closer verticallythan is shown in the drawings.

It will be seen that the two rods E and F, besides having independentmovements, can be made interchangeable, the onterrod being suited tohold the projecting arms to move the indices, and the inner rod beingsuited to hold the projections to engage the tops of bellows. The numberof the indices can be increased or lessened, as desired. It will also beseen that when it is intended to have the rising of rod E to cause thewhistle to sound, instead of ringing the bell,i ts upper end may be madein form to force air through the whistletube, as may be seen in Fig. fl,said whistle, with its supporting -brackets J, taking the place of thebell mechanism with its supportin gbrackets J.

I do not confine myself to the exact mechanism as herein set out, asthere are other constructions of an annunciator, either pneumatieally orelectrically operated, that can be made in which the tubular rod E andits supplemental rod F can be used.

Should at any time too great force be brought within the bellows bysudden or too great an influx of air, the bellows can be madeself-relieving of pressure by putting a small hole between the two upperor smaller folds, as during the rise of a tapering bellows its foldsmove in succession, and not simultaneously, the largest one moving firstand the others following, to the smallest, and so the hole would be keptclosed at the inner edge of these folds till after the bellows hadperformed its other functions.

The brackets R (shown in Figs. 7 and S) are the ones used in operatingthe device.

The operation of the device by electricity needs scarce any description,as when the electric fluid in any of the well-known ways, through themedium of the wires S, is made to cause the magnet O to attract an armof the lifting-rod E such rod will rise with the result as beforestated.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. The combination, in an annunciator, of a case with an alarm attachedthereto, and a pivoted index and a vertical moving hollow lifting-rodsupported upon a face of said frame, said hollow lifting-rod having aslot in its side, and a projecting arm E,by which it is actuated, asupplemental rod 1 adapted to work within such hollow rod and having anarm 1 passing through and adapted to work within such slot, saidlifting-rod having independent motions, the one upon its one movementadapted to sound the alarm, and the other by its engaging-arm beingadapted to restore said index to its normal position, and operativemeans, substantially as and for the purposes set forth.
